Abstract

This study was conducted to investigate the effect of sub-ingredients of kimchi on the formation of carbon dioxide and vessel pressure. The pH, titratable acidity, formation of carbon dioxide and vessel pressure of kimchi prepared with different sub-ingredients were determined during storage at 10$^{\circ}C$. In the kimhi without GA, the pH decrease and acidity increase was slow during storage, but those of the kimchis without Gl, RP and SA were began to higher from 3th day after storage showed maximum values and was maintained 9th day after storage. The main sub-ingredient for formation of carbon dioxide was garlic and the gas formation was low in the kimchi without garlic. Vessel pressure in kimchi of the latter term of storage generally showed sub-atmospheric pressure and the more formation of carbon dioxide showed the more degree of sub-atmosphere.

재료조성이 김치의 저장 중 탄산가스 발생과 용기 압력에 미치는 영향을 조사하기 위하여 재료조성을 달리한 김치를 1$0^{\circ}C$ 에서 저장하면서 pH, 산도, 탄산가스 발생량 및 용기압력의 변화를 측정하였다. 그 결과 마늘을 뺀 김치는 pH감소와 산도의 증가가 완만하였으나 생강, 고춧가루, 젓갈을 뺀 김치는 크게 촉진되었다. 탄산가스 발생량은 대조구와 생강, 고춧가루 및 젓갈을 뺀 김치에서는 저장 3일째부터 높아지기 시작하여 저장 6일째에 최대 값을 나타내었으며 저장 9일째까지 발생이 지속되었다. 김치 담금 재료 중 탄산가스 발생 을 주도하는 재료는 마늘로서 이를 뺀 김치에서는 탄산가스 발생량이 낮았다. 용기압력은 대조구와 생강을 뺀 김치에서 높았으며, 고춧가루, 마늘 및 젓갈을 뺀 김치에서는 비교적 낮았다 또 저장후기에는 전반적으로 감압 상태로 전환되었으며 탄산가스 발생량이 높을수록 감압도가 높았다.
